He made three Swift (http://www.engadget.com/2015/06/08/swift-open-source/) apps that use the Apple Pencil in new ways (http://www.macrumors.com/2015/11/23/apple-pencil-scale-synthesizer-3d-controller/): as a synthesizer powered by AudioKit, in an image-editing program and as part of an electronic scale. PencilSynth (http://flexmonkey.blogspot.co.uk/2015/11/pencilsynth-apple-pencil-controlled.html) uses the Apple Pencil's position on the iPad Pro to control the sound emitted, changing pitch and frequency as the Pencil travels at different angles across the screen. PencilController (http://flexmonkey.blogspot.com/2015/11/pencilcontroller-using-apple-pencil-as.html) offers three image-filtering modes (hue/saturation, brightness/contrast and gamma/exposure), each controlled by holding one finger on the appropriate mode key and moving the Apple Pencil around a pivot point on the screen.PencilScale (http://flexmonkey.blogspot.com/2015/11/pencilscale-using-apple-pencil-with.html) is the most "experimental" of Gladman's projects, using the Apple Pencil as a stand for a series of weights sitting directly on top of a scale app. Gladman calls PencilScale "sensitive, but not terribly accurate."
